No service delivery for most expensive television

I received a call from DSTV and was offered the Explora deal. Already had the HD decoder plus dual view activated to account. Decided to take the offer. Decoder arrived, contacted Multichoice in Tzaneen to install. Was told decoder was in the name of another customer residing somewhere in Natal. Was then told that I have to receive a new decoder, one in my name. A month almost went by with no further feedback. I contacted DSTV head office to cancel offer. It was said that the decoder is now registered to me. No call to advise me. Since the installation, month on month the account is suspended. I log calls and I'm still waiting for a supervisor to contact me. I arrived home shortly before 23:00 PM on 02/07/2015 and service suspended because account in arrears. On the 25/06/2015, an amount of R813.00 was debited, what happened to R799.00. Cancel this awful deal and come collect your junk!!!! Always quick to take money, no after sale service, but then again that's typical in today's living invironment!!!
